SPECIFICATION forming part of Letters Patent No. 643,567, dated February13, 1900.

Application filed August 1899.

, which are hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my device, certain of the supportingpiles or posts being broken away to better show the working parts. Fig.2 is a plan of the same; and Figs. 3 and 4 are cross-sections taken,respectively, upon the lines 3 3 and 4 4 of Fig. 1.

The object of my invention is to produce a device which shall beeconomical in construction and not liable to derangement by storms andwhich shall be adapted to utilize the power of the rise and fall and thebackward and forward movement of the waves. With this object in View Ifirst construct a framework consisting of longitudinal timbers A, whichare supported upon piles B, which are driven into the water and extendto a considerable distance above the same. These piles and longitudinaltimbers A are connected by any suitable system of cross-bracing, so asto form a structure which will stand the effect of storms. Thisstructure extends out over the water, even at low tide, and has beneaththe same one or more floats O C, the number of floats used dependingupon theamount ofpower required.

The floats are connected with the frame A by means of levers or links DD, which are pivoted to the lower side of the frame and to the upperside of the float. These links permit the float to rise and fall and toat the same time have a swinging motion longitudinally of the frames A.

Upon the frame A and above the float O is journaled a shaft F, whichextends transversely of the frames and of the direction of Serial No.727,306- (No model.)

movement of the float 0. Upon this shaft are fixedly secured aratchet-Wheel G and a pulley-wheel H. Two levers I and I are journaledconcentric the shaft andextend in opposite directions therefrom. Theselevers may be journaled directly upon the shaft F, but preferably arejournaled upon sleeves F, which surround the shaft and are secureddirectly to the frame. These sleeves are shown in cross-section in Fig.3.

Upon the outer ends of the levers I and I are placed pawls g, which areheld in engagement with the teeth of the ratchet-wheel G by means 'ofsprings g. The two levers I and I are connected with the float by meansof links E, which are pivoted to said levers and to the floati As thefloat swings in one direction under the influence of the wave the pawl 9upon one of the levers will engage the teeth of the wheel G to turn itin one direction, and when the float 0 moves in the opposite directionthe other pawl g will be moved so as to engage the teeth and turn thewheel. 7 The float 0 thus acts to turn the wheel G both in its upwardand downward movement.

I have herein shown two floats O and O, which are connected to shafts F,located upon the frame in an exactly similar manner.

At another point upon the frame a short shaft K is journaled, the saidshaft being provided with a pulley-wheel L,secured thereto, and havingtwo ratchet-Wheels L, secured to opposite sides thereof. Theseratchetwheels might, if desired, be made separate from the wheel L andfixedly secured to the shaft. It, however, makes the construction morecompact to have the ratchet-wheels secured to the side of thepulley-wheel L.

Upon the outer sides of each of the ratchetwheels L are placedpulley-wheels Mand M, said pulleywheels being mounted loosely upon theshaft K and being connected, re spectively, with the pulley-wheels H andH, mounted upon the two shafts F, by means of ropes or belts h and h.

By multiplying the number of floats a more even and steady power isdelivered than is possible where only a single float is used. Thedevice, however, will work satisfactorily with a single float, althoughin such case it is desirable that the pulley-wheel L be made ofconsiderable weight, so as to act as a flywheel to carry the motion pastpoints where power is not being delivered thereto from the float. Poweris conveyed from the flywheel L by means of a cable N, which passes oversaid wheel and connects with a suitable wheellocated upon shore or uponanysuitable fixed structure.

This device may be used for any purpose for which power is desired,either for pumping water, running machinery, generating electricity, orany of the usual purposes for which power is desired.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A wave-motor, comprisinga frame above thewater, a float, a set of arms pivoted to float and frame, and permittingthe float to swing iii the direction of movement of the waves, a shaftjournaled on the frame, a lever pivoted concentric with said shaft and abar or link pivoted to the outer end of said lever and to the float, anda clutch connection between the lever which is journaled concentric theshaft and the shaft to rotate it, substantially as described.

2. A wave-motor, comprisinga frame above the water, a float, a set ofarms pivoted to float and frame and permitting the float to swing in thedirection of movement of the waves, a shaft journaled on the frame, aratchet-wheel secured to the shaft, two levers pivoted concentric withsaid shaft and extending in opposite directions therefrom, a pawl oneach lever engaging opposite sides of the ratchet-wheel, and links orbars connected to the outer ends of said levers and to the float,substantially as described.

3. A wave-motor, comprising a frame above the water, a float, a set ofarms pivoted to float and frame, and permitting the float to swing inthe direction of movement of the waves, a shaft journaled on the frame,a ratchet-wheel and a belt-wheel secured to said shaft, two leverspivoted concentric to said shaft, pawls on said levers engaging theratchet-wheel, links or bars pivoted to the outer ends of said leversand to the floats, a second shaft journaled on the frame and having afly-wheel, and a ratchet-wheel secured thereon, a belt-wheel looselymounted on the same shaft and: carrying a pawl adapted to engage theteeth of the ratchet-wheel, and a belt connecting the belt-wheels uponthe two shafts, substantially as described.

4:. A wave-motor, comprisinga frame above the water, a float, a set ofarms pivoted to float and frame and permitting the float to swing in thedirection of movement of the waves, a shaft journaled in the frame, aratchet-wheel and belt-wheel secured to said shaft, sleeves secured tothe frame and surrounding the shafts, two levers pivoted upon saidsleeves and extending in opposite directions from the shaft, pawls onsaid levers engaging the ratchet-wheel, and links or bars pivoted to theouter ends of said levers and to the floats, substantially as described.

5. A wave-motor, comprising a frame above the water, a float, a set ofarms pivoted to float and frame and permitting the float to swing in thedirection of movement of the waves, a shaft journaled in the frame, aratchet-wheel and belt-wheel secured to said shaft, sleeves secured tothe frame and surrounding the shafts, two levers pivoted upon saidsleeves and extending in opposite directions from the shaft, pawls onsaid levers engaging the ratchet-wheel, links or bars pivoted to theouter ends of said levers and to the floats, a second shaft journaled onthe frame and having a fly-wheel, and a ratchetwheel secured thereon, abelt-wheel loosely mounted on the same shaft and carrying a pawl adaptedto engage the teeth of the ratchet-wheel, and a belt connecting thebeltwheels upon the two shafts, substantially as described.
